FUMIGATING'APPARATUS.

SPECIFICATION forming part of Letters Patent No. 558,258, dated April 14, 1896. Application filed May 20,1895. Serial No. 549,858. (No mam T0 aZZ whom it may concern.-

Be it known that I, EDWARD O. COLSON, a citizen of the United States, residing in Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Fumigating Apparatus, of which the following is a specification.

My invention relates to an apparatus for fumigating rooms or buildings and their contents.

The object of my invention is to provide a simple, inexpensive, and efficient apparatus for fumigating rooms, buildings, furniture, apparel, and other articles for the purpose of destroying disease germs.

In my invention the rooms or objects to be.

from the heated water may all be intermingled and combined before being delivered from the apparatus into the room to be fumigated.

It further consists, in connection with these parts, of inlet and outlet conductor-pipes for connecting the apparatus with a room, so as to form a complete circuit or system of circulation between the apparatus and the room or building to be fumigated in cases where the apparatus is not placed directly in the room being fumigated.

It further consists in the novel combinations of parts and devices herein shown and described, and more particularly specified in the claims.

In the accompanying drawings, forming a I part of this specification, and in which similar letters of reference indicate like parts in in all the views, Figure 1 is a side elevation of an apparatus embodying my invention. Fig. 2 is a central vertical section. Fig. 3 is a vertical section on the line 3 3 of Fig. 2. Figs. 4 and 5 are horizontal sections on lines 4 4 and5 5, respectively, of Fig. 2. Fig. 6 is a detail perspective outline view of the grate turned upside down. Fig. 7 is a detail view of the combined leg and bolt, and Fig. 8 is a central vertical sectional view of a modification.

In the drawings, A and B are two shells, preferably of a cylindrical form and made of sheet metal, fitting one within the other with an open space 0 between them.

D and D are upper and lower frame-rings, preferably made of cast-iron and provided with flanges or shoulders d (1 to receive and hold in place the cylindrical shells A B when said rings are clamped together by the bolts E E, which are furnished each with integral extensions E to serve as the legs for supporting the apparatus. lhe leg-bolts E E have offsets or shoulders E to bear against the lower frame-ring D.

F is an annular sulfur-receptacle, G an annular receptacle for the tobacco or tobacco stems, and H a central pot or receptacle for Y the water. The sulfur and tobacco receptacles F G are preferably formed of cast-iron and in one piece and are supported within the cylinder B near the top thereof by a series of lips or projections f on the castdouble annular pot F G, engaging an internal annular bead or shoulder 12 on said cylinder B, the open spaces f f between the lips ff serving as the means of communication between the mixing-chamber K above the sulfur, tobacco,

and water receptacles F G H and the charcoal-chamber L, and N is the dome or cover inclosing the mixing chamber K.

The water-receptacle H is preferably formed in a separate piece fromthe annular casting F G.. It is, however, preferably secured to this casting, this being conveniently done by the bail h, the ends h of which are passed down through or below the inner peripheral edge g of said annular casting F G. The water-receptacle H has an annular shoulder 72.2 to support it on the annular casting F G and permit it to project down into and through the central opening g in said casting into the charcoal-chamber and be heated by the burning charcoal the same as the sulfur and tobacco receptacles.

The grate M may be of any suitable c011- struction; but I preferably construct it of wire-netting, the most convenient way being to take a piece of wire-netting of a square form and shape it to fit within the cylinder B and at the same time turn its corners on down to form legs or supports for the grate. The grate M rests upon the bottom plate P of the apparatus, which rests upon the lower frame-ring D.

R is the inlet-pipe leading from the lower portion of the room. to be fumigated to the apparatus, and R is the outlet-pipe leading from the apparatus to the room, as indicated in Fig. 1, so that a continuous circulation may be produced to and from the room through the apparatus, and S is the coupling or connecting pipe to whichthe inlet-pipe R is connected and which communicates with the upright fines C, preferably three in number, which communicate with the mixing-chamber K. The flues C are formed in the open space 0 between the cylinders A B, the inner cylinder B being provided with openings or ports 1), leading into the mixing-chamber, and the lower frame-ring D having openings (Z to receive the flue-stubs s on the coupling-pipe S. The coupling-pipe S extends preferably about two-thirds of the way around the cylinder, so that the three flues C may be equally disposed about the circumference of the apparatus. The outlet or return pipe R communicates with the mixing-chamber K, the dome or cover N having a central nozzle or coupling N at the top thereof.

0 (J are short fiues also formed in the open space between the cylinders A B and communicating, through openings or ports 11 b in the inner cylinder B, with the ash-pit or chamber M beneath the grate to supply fresh air to the burning charcoal to support the combustion and thus afford a continuous supply of carbonic-acid gas or products of combustion of the charcoal to mix in the mixing chamber K with the fumes arising from the burning sulfur F and tobacco G and the vapor from the water H.

To prevent undue heating of the inner cylinder B and injury to the apparatus, the space G between the cylinders A B not occupied by the flues O C is left free for the air to circulate through the same, this being effected by providing the upper and lower rings D D with openings or perforations (i As shown in Fig. 1, the apparatus is set up outside of the room X to be fumigated; but bysimply disconnecting the circulating-pipes R R the apparatus may be placed inside the room and be there operated without further change, though ordinarily for operating inside a room I also remove the coupling or connecting-pipe S, so as to give more direct entrance to the inlet-fines C for the air of the room.

In the modification shown in Fig. 8 the separate receptacle G for the tobacco is omitted, the tobacco or the juice or extract thereof being in this construction mixed with the water and placed in the water-receptacle H. This modified construct-ion is more particularly designed for placing inside the rooms tobe fumigated, and the pipes R R and coupling S are also omitted. 3y this means it will be seen that the air from the room entering the mixing-chamber K is there subjected to the combined and intermingled fumes arising from the burning charcoal, sulfur, and tobacco mixed with the vapor of water, and thereby rendered effective in destroying disease germs. As the products arising from the burning charcoal enter the mixing-chamber in an annular series of individually-separated streams through the annular series of openin gs f at the periphery of the inixingcliamber 1 and are then deflected centrally or radially inward over the annular streams or masses of I fumes arising from the annular sulfurrecep- I tacle and from the annular tobacco-receptacle before reaching the central outlet, and are 2 thus mixed, and must also pass directly over the central water-receptacle and become satuclients or agencies.

1 rated or mixed with the vapor arising therefrom, it is obvious that the diiferent vaporous prod ucts will become thoroughlyintermingled and mixed together; and as the air from the room to be fumigated is led peripherally into this mixing-chamber and must pass radially over or across the annular streams or masses of fumes arising from the annular series of receptacles it follows that it must be thoroughly acted upon by all the different ingre- It will be observed that as the products from the charcoal arise ,around the peripher Y of the sulfur-receptacle F, though the charcoal-receptacle is located below the receptacles F G H, the effect 1 is that of four concentric receptacles having a common central outlet or discharge at the central opening 11- of the dome or cover N, while at the same time the heat produced by 1 the combustion of the charcoal is utilized as the means of heating the receptacles F G H.
